Electric-dipole active two-magnon excitation in {\textit{ab}} spiral spin phase of a ferroelectric magnet Gd $_{0.7}$ Tb $_{0.3}$ MnO $_{3}$

N. Kida, Y. Yamasaki, R. Shimano +2

A broad continuum-like spin excitation (1--10 meV) with a peak structure around 2.4 meV has been observed in the ferroelectric $ab$ spiral spin phase of Gd $_{0.7}$ Tb $_{0.3}$ MnO $_{3}$ …

Metal-insulator transition in $(L a M n O_{3})_{2 n} / (S r M n O_{3})_{n}$ superlattices

Shuai Dong, Rong Yu, Seiji Yunoki +3

The modulation of charge density and spin order in (LaMnO $_{3}$ ) $_{2 n}$ /(SrMnO $_{3}$ ) $_{n}$ ( $n$ =1-4) superlattices is studied via Monte Carlo simulations of the double-exchange model. G…

Novel Quantum Criticality in CeRu $_{2}$ Si $_{2}$ near Absolute Zero Observed by Thermal Expansion and Magnetostriction

J. Yoshida, S. Abe, D. Takahashi +6

We report linear thermal expansion and magnetostriction measurements for CeRu $_{2}$ Si $_{2}$ in magnetic fields up to 52.6 mT and at temperatures down to 1 mK. At high temperatures, thi…

Enhanced spin Hall effect by resonant skew scattering in orbital-selective Kondo effect

Guang-Yu Guo, Sadamichi Maekawa, Naoto Nagaosa

The enhanced spin Hall effect in Au metal due to the resonant skew scattering is studied with first-principles band structure calculations. Especially the gigantic spin Hall angle…

Quantum spin Hall effect in a transition metal oxide Na2IrO3

Atsuo Shitade, Hosho Katsura, Jan Kunes +3

We study theoretically the electronic states in a $5 d$ transition metal oxide Na $_{2}$ IrO $_{3}$ , in which both the spin-orbit interaction and the electron correlation play crucial role…

Origin of the multiferroic spiral spin-order in the RMnO3 perovskites

Shuai Dong, Rong Yu, Seiji Yunoki +2

The origin of the spiral spin-order in perovskite multiferroic manganites $R$ MnO $_{3}$ ( $R E =$ Tb or Dy) is here investigated using a two $e_{g}$ -orbitals double-exchange model.…
